frame differences? c10 to c20 and c10 to c10burban??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ok i must be over looking something, i was looking up headers on summits web site and they say they will fit a 71 c-20 pickup and a 71 c-10 burban but wont fit a 71 c-10 pickup.

Whats the difference in the frames to cause this problem? for some reason i was under the belief that c10 and c20 frames were the same, i guess i was wrong (witch isnt to uncommon).

Thanks

no, you're right.
C/10 and C/20 frames are the same with just a couple exceptions;
cab mounts are lower to accept taller bushings
added braces on coil spring /trailing arm mounting points
Burb frames are not the same, but I think all the differences are in the back.

Longhorn man: Thank you! so If they say headers will fit a 454 c-20 and a c-10 burban they should more then likly fit my 454 c-10 shortbed?

Thanks

The c/20 frames are a bit wider (from pass side to driver's) near ther rear axle than the k/10s

we are compairing C10 to C20... not C to K. The K series has a totally differant frame.

Rat, if your big block is mounted properly, then yes, the headers should work.

yeah i know the c to k frames are totally different, but thats good news they should work.... well its time to save some coin for headers!
